Delivery was quick. Ordering was easy. Product mixes easily and tastes good. Glad I no longer have to take all those plastic capsules.

Mixes easily and tastes good. Much better than taking a handful of plastic capsules everyday.

Haven't used it long enough to say how good it works. Can say it shipped to me in good time, it mixes easily, and tastes OK.. Better than taking a handful of capsules every day.

Also mixes in water very easily. I've been using a little over a week before and during workout and seems to give noticeable increase... (great pump!).

In my research of arginine products came across a web site that reviewed some of the current products on the market.. forbiddenknowledge.info/arginine.html interesting.. Makes the point that you want a pure product.. This is it and at a price point that is worth every penny. ..... So far I'm impressed with the product and feel great. Mix it in with the water for a couple of minutes and let the powder completely dissolve. The taste is not bad at all..
